Abstract

original image

An array of passive Au antennae (whose magnified image is shown in the background) fabricated on an all-protein-based silk substrate were conformally transferred and adhered to the surface of an egg by F. G. Omenetto and co-workers. The process allows for intimate contact of micro- and nanostructures that can probe their surrounding environment, and accordingly provides the opportunity for in-situ monitoring of food quality. This type of device is composed entirely of edible and biodegradable components, making it well suited for interfaces with biological matter. For more details, see page 1067.
